Uridine triphosphate (UTP ) is a nucleoside triphosphate with uracil. It is an RNA component that is incorporated with the elimination of two phosphate groups in the RNA, and serves as a coenzyme for the activation of sugars to be incorporated in polysaccharides. For this purpose it binds hexoses to form an ester, so that a UDP hexose.

The transesterification from UTP and glucose-1 -phosphate to UDP-glucose and pyrophosphate activated D-glucose for installation in Glykogenpolymere ( surplus sugar is stored as glycogen in animals ). In the isomerization of D- galactose, UDP-galactose to glucose is first formed, which is then converted to UDP -glucose. This gives her the next UDP galactose on.
